Tectonic setting of the world's giant oil fields ///

Although there are large variations in reserve estimates, giant fields contain at least 65% of the world’s proven reserves. Therefore, knowledge of their tectonic setting, geologic history and conditions for hydrocarbon formation will contribute greatly to understanding the origin and future supply of the world’s hydrocarbons. Six areas ranging from Siberia to the Asia-Pacific where giant fields are densely clustered are presented. The authors discuss how the tectonics of these particular areas produced these clusters and their rationale for classification.
